A high fever with a cold and severe body pain is usually due to a viral infection, such as the flu, causing severe weakness. Take complete rest, drink plenty of warm fluids, keep yourself covered, eat light food, and use simple fever relief if already advised to control symptoms. Do steam inhalation, stay hydrated, and monitor your temperature and any signs like weakness or dizziness. If the fever stays high, you feel very weak, or new symptoms appear, try to contact a doctor by phone or seek nearby help for proper care.
